There are three possibilities 1) Nomodeset option. Not very good, graphics don't look good. 2) UXA option. Works, graphics is reasonable, but only one screen available. the second screen doesn't seem to work on my test machine 3) server-xorg-video-intel option. Graphics is the best, performance on playing video was the best.. Also only one screen available. Tests were performed on an older Lenovo T60 laptop. with T2400 processor, 4 Gig ram Xubuntu 16.04 on the internal hard disk, Lubuntu 16.04 on the external hard disk I did two tests, first test I compared the performance with two videos 1280x 720 resolution, one H264 encoded .mp4 and the second a H265 .mp4 encoded video also 1280 x 720 Here are the results. I did the test with UXA and I uninstalled server-xorg-video-intel (effectively comparing option 2 against option 3 The cpu load with taskmanager was slightly higher with UXA acceleration on Gnome Mplayer as well on the H264 as well on the H265 encoded video However the video rendering is definitely less smooth with UXA acceleration on the H264 video. Especially with a person walking next to a window the rendering was more jerky. It was clearly noticeable. On the H265 video on the H265 video the difference was even more. Quite jerky with an average CPU load of around 55%, before with the xserver-xorg-video-intel the CPU load was around 50% On VLC the difference was even worse the H264 which worked a bit jerky before was now extremely jerky and the H265 video simply got stuck Conclusion: from the test results I must say that that xserver-xorg-video-intel gives the best results Also I compared on the same machine the performance between Xubuntu 16.04 and Lubuntu 16.04 with the xserver-xorg-video-intel option (same videos as mentioned before). Two videos tested, H264 encoded .mp4 and H265 encoded .mp4, they are 720p videos 1280 x 720 (encoded with Shotcut) Lubuntu 16.04 plays both videos fine with the native Gnome Mplayer, both H264 and H265 On VLC only the H264 video plays but jerky, the H265 video doesn't play well at all. On Xubuntu 16.04 the H264 video plays fine with the native Parole player The H265 video plays very jerky with the native Parole player On VLC both videos don't play well at all. Conclusion: Lubuntu 16.04 with the xserver-xorg-video-intel works better playing movies than Xubuntu 16.04</div><div> <div><div><div><div>Met vriendelijke groet / Best regards, Jan Holtman <a href="mailto:1%3Aoulik.jan@gmail.com" target="_blank">oulik.jan@gmail.com</a> <a href="mailto:2%3Ajan.holtman@live.com" target="_blank"></a></div></div></div> <div class="gmail_quote">---------- Forwarded message ---------- From: Nio Wiklund <<a href="mailto:nio.wiklund@gmail.com" target="_blank">nio.wiklund@gmail.com</a>> Date: Tue, May 10, 2016 at 8:44 PM Subject: Re: Fwd: [lubuntu-devel] Missing Intel graphic drivers on 16.04 To: Jan Holtman <<a href="mailto:oulik.jan@gmail.com" target="_blank">oulik.jan@gmail.com</a>> Hej Jan, Thank you very much for this test :-) I suggest that you share the results (also specifying the graphics chip) 1. with the Lubuntu mailing lists and Julien lubuntu user list <<a href="mailto:Lubuntu-users@lists.ubuntu.com" target="_blank">Lubuntu-users@lists.ubuntu.com</a>> lubuntu-devel <<a href="mailto:lubuntu-devel@lists.ubuntu.com" target="_blank">lubuntu-devel@lists.ubuntu.com</a>> and the Lubuntu main developer julien Lavergne <<a href="mailto:gilir@ubuntu.com" target="_blank">gilir@ubuntu.com</a>> 2. in your thread at the Ubuntu Forums. (I want *you* to get the credit for the testing. By the way, my tests with my old IBM Thinkcentre ranks the methods in the same way.) -o- This means that I will make a new Lubuntu system with xserver-xorg-video-intel that I will recommend as the first choice. The UXA system might work in some cases, it might still be available as a second choice. I intend to make a tarball for the One Button Installer and a compressed image file (for several cloning tools, e.g. mkusb).

Just one thing to have an accurate comparison, and save some time it would maybe better to uninstall xserver-xorg-video-intel at the existing system and to rename *OLD__xorg.conf__OLD *back to *xorg.conf* Then we have an accurate comparison, what do you think? Because the same software is installed with the same programs codec etc. In the past I did hardware and software testing in my previous job. One last thing: As you know there is only one screen available with both the UXA option as well with the xserver-xorg-video-intel option. I will try to test tonight.

Even ARandR will not see the second monitor It looks to me that we are definitely on the right track.
